PV Grid Connected Inverters

PV Grid-Connected Inverters 100KW

General Descriptions:SG100K3 is using low-frequency isolation transformer for indoor applications. It can be continuously operating at rated power under +55°C without derating. It is the ideal product used for string-connected large PV power station to simplify PV power plant design. In addition, wider input voltage range ensures more combinations of the PV arrays. It is one of the highest cost-effective grid-connected inverters in the world.Technical Features: • Reactive Power Control with power factor from 0.9 lagging to 0.9 leading • German BDEW medium voltage guideline compliant • Max. efficiency at 97.0% • Using advanced IGBT modules • Easy Installation and maintanence • Precise output power metering • Multilingual LCD display • Auxiliary heater (optional) • Continuously operating at rated power under +55°C without derating • Max. working altitude at 6000m (operation with derating above 3000m) • TÜV, CE, Enel-GUIDA certificationCommunications: • RS485/Ethernet/GPRS interfaces • Computer monitoring softwareSafety:·Full protection functions: over-voltage protection, short-circuit protection, islanding protection, over-heat protection, over-load protection·Standards complied: EN61000-6-1, EN61000-6-2, EN61000-6-3, EN61000-6-4,EN61000-3-2, EN61000-3-3, EN60164-1-1,EN55022, EN50178, TÜV, Enel-GUIDA
